Encounter – The Audi Technology Magazine 2/2015
The underside of the new Audi A4 features targeted airflow guidance. The engine bay is encapsulated and there are large areas of cladding beneath the occupant cell and luggage compartment. The rear axle suspension arms are specially covered, while small spoilers – including those in front of the wheels and on the fuel tank – guide the airflow. Lift at the rear axle is very low.
